Legacy Token authentication failure after system authentication update

Summary
Between February 16 and 17, 2026, some customers using older API tokens experienced authentication failures. These tokens, originally created before a recent system update, could not be used to access services. Tokens issued after the update were not affected. The issue was caused by the removal of a process that allowed continued use of these older tokens. The problem was identified overnight and resolved the following morning.
